Antonio Brown has left the building.
In one of the strangest moments of the 2021 season, the Buccaneers wide receiver abruptly removed his shoulder pads and undershirt and jogged to the locker room at MetLife Stadium during the third quarter of Tampa Bay's Week 17 matchup with the New York Jets.
Here's video of the scene, which shows Brown stripping off his pads, throwing his undershirt and gloves into the stands, and running toward the locker room in the middle of the game while the Bucs were on offense.
Brown, who had three catches for 26 yards on five targets at the time, apparently "boiled over" and was "very upset" on the sideline, according to FOX sideline reporter Jen Hale.
Another angle of the incident filmed by a fan in the stands shows wide receiver Mike Evans trying to reason with Brown before he made his sudden exit.
It appears head coach Bruce Arians benched Brown, which led to the former New England Patriots wide receiver's outburst.
UPDATE (5 p.m. ET): Arians told FOX Sports' Jay Glazer after the game that he actually was trying to get Brown to enter the game before his departure.
Brown served a three-game suspension in December for violating the joint NFL-NFLPA COVID-19 protocols after he misrepresented his vaccination status. He tallied 101 receiving yards on 10 catches last Sunday and appeared to be back in the Bucs' good graces, but there's a good chance that changes after Sunday's incident.
